A COMPARATIVE STUDY OF THEORETICAL AND NUMERICAL SIMULATIONS OF TRAPPED WAVES INDUCED BY STORM SURGES
风暴潮引起的地形诱导波的理论与数值对比研究

The following characteristics of this process have been determined. 1 ) Typhoon approaching the coastline at about 30° causes Waves With isochrones of peak surge elevations parallel to the coastline. 2 ) If waves with specific parameters enter the analysis area through the southern boundary, then they are propagated northwards with uniform phase speed, but not in the off-shore direction. 3 ) Initial disturbances in the middle of the analysis area near the coast lead to waves propagating in all directions. Maximum elevations decay much quicker to the east than to the south or the north. 4 ) The agreement between the phase speed deduced from an theoretical analysis and the numerical model is good.
